First, I don't want to offer any encourage any one to try aerobatics
except in a plane rated for them.

The way I see it, virtually any *basic* aerobatic maneuver can be done
without causing undue stress in a good portion of normal and utility
category aircraft. The twin is a different animal due to inertia and
the weight out there on the wings., but Bob did an outstanding job. If
anything he may have made it look too easy:-))


The snap roll is normally considered a bit hard on airplanes, but I've
seen a number of rag and tube aircraft do snap rolls nose high and at
a low speed. The "Flying Farmer" used to do a routine with a number
of snap rolls, but they sure weren't the ones most people think of
when they see air show performers doing snap rolls at higher speed.
"Those things are uncomfortable"

Almost any single engine plane could do a hammer head, but be a bit
late and you may have to walk home if it leads to a tail slide. :-))

Barrel rolls are probably one of the easiest maneuvers to learn and
the easiest to screw up.

However after reading the subject line and original post I keep
wondering how you have a mid-air accident by your self? Is it half
way between the top and bottom, or the edges. I can see how top and
bottom are defined although I've never flown anything capable or
coming near the top and the bottom adds new meaning to "hard deck".
I've just never been able to figure out where the sides are located.


The crash of this P-68 was way back in the '80s here in the U.S. The
guy was doing aerobatic demos to show the airplane off for, IIRC, the
Partenavia factory.

The NTSB report says he pulled just over 8G and pulled the wings off.
If you had the original audio you could hear his wife narrating his
flight....sad.
